Cardiac output = 5.0 L/min
To the right is a diagram of circulation through many of your major organs when your body is at rest. Answer the following questions:
Lungs
During a fight-or-flight response, your body changes how much blood it sends to different organs. Draw x's through the arrows on the right side to depict which organs will receive less blood flow. Then, in 1-2 sentences, tell me how your sympathetic system shuts off blood flow. (5 points)
Brain: 55 mL/100g/min
70 mL/100g/min
Liver and digestive tract: 100 mL/100g/min
400 mL/100g/min
Skeletal muscle: 5 mL/100g/min
In 1 sentence, tell me what happens to total peripheral resistance while this fight-or-flight response is occurring. (2 points)
10 mL/100g/min
Bone and other tissue: 3 mL/100g/min
During a fight-or-flight response, mean arterial pressure tends to increase. Will this cause blood to flow into the veins and back to the heart faster or slower? Why? (2 points)
